HANDCUFF.

SPECIFICATION forming part of Letters Patent No. 470,869, dated March15, 1892, Application filed June 8, 1891- Serial No. 395%56. (No model.)

To all whom it may concern;

3e it known that I, HENRY W. KAHLKE, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented an Improvement in Handcuffs, of which the following is aspecification.

Difficulty has been experienced from prisoners hammering against theprojectingen d of the hasp until the bolt or latch holding the same 1sbroken or until the projecting end of the segmental hasp is broken off.

My present invention is designed to lessen the opportunity of contactwith the end of the hasp by providing two hasps swinging in oppositedirections and approximately close together, so that the projecting endof one hasp 1s shielded by the arc portion of the other hasp, and thebolts or catches are made in such a manner that one boltis operativewith the two spring-latches to hold the springlatches, so that theycannot be withdrawn until the bolt is drawn back and the same bolt isavailed of in Withdrawing the springlatches for opening the handcuff.

In the drawings, Figure 1 is an elevation,

partly in section, of the handcuff complete.

Fig. 2 is a cross-section at the line 00 00. Fig. 3 is a horizontalsection at the line y y. Fig. 4 represents acover to the lock-case, andFigs. 5 and 6 represent the parts of the bows and latches in theirdifferent positions.

The case A is of desired size or shape and recessed for the reception ofthe parts of the lock, and the cap-plate A is applied to cover the partsof the look after they have been put in position, and such cap-plate ispreferably secured by riveting up the studs 2 3 4E, and in thiscap-plate is the key-hole5, and 6 is the stud for the key.

The haspsB and B are similar in construction, and they are connected tothe case A at the joint 0, which joint is preferably a pin passingthrough the respective hasps and through the projection of the case, asindicated in Fig. 2, such pin having heads and being riveted up, asrepresented.

The hasps B and B are made with are pieces or segments 7, notched intheir inner surfaces, and these arc pieces swing approximately closetogether and pass through the case A from opposite directions, and hencewhen the two ends of the are pieces are within the holes that areprovided for them in the case A they are supported thereby, and when thehasps are pressed toward the case, so as to close the handcuff aroundthe wristor wrists of the prisoner, the arc portions of the hasps,projecting in opposite directions from the case, are shielded by the arcportions of the adjoining hasps, so that they are less liable to beinjured by concussion upon or against the projecting ends of such hasps.

The latches D D are upon the studs 2 and 3, respectively, and theselatches are provided with springs 8, which tend to throw the catches 9of the latches into the notches of the are 7, and there are upon thelatches D D the fingers 10, and the bolt E is provided with a projectingflange 11, which is adapted to pass in between the catches 9 when theyare projected by the springs into the notches of the hasps, so that whenthe flange 11 of the bolt is in the position shown in Fig. 1 the latchescannot be withdrawn, but are blocked firmly. When the bolt is in theposition shown in Fig. 5, the latches D D are free to move under theaction of their springs, and hence the hasps can be rapidly forced intoplace and they will be caught by the latches D and D automatically, andwhen the latches D D are to be withdrawn the boltE is moved back intothe position shown in Fig. 6, so that the flange l1, acting upon thefingers 10, swings the latches D D and draws them back from contact withthe hasps. Hence the shackle or handcuff can be opened freely.

The bolt E is of any desired character. It is, however, provided withtwo projections or talons for the key Gto act upon, so that when the keyG has been rotated in the direction indicated by the arrow in Fig. 5 thebolt E will have been withdrawn from the position of Fig. 1 to theposition of Fig. 5, and when the rotation of the key is continued for asecond turn from the position of Fig. 5 to that of Fig. 6 such key willact upon the second talon of the bolt to draw such bolt back into theposition of Fig. 6 and open the handcuff.

The tumblers made use of in this look may be of any desired character. Ihave represented sprin g-tumblers H, that are notched for the stud 12 onthe bolt, and I remark that the number of tumblers and the shape of thekey may vary and do not form a necessary part of this improved handcuif.I have, however, found that it is advantageous to make use of threetumblers and to use a key that has a pipe to set upon the stud 6, asthis construction lessens the risk of the lock being picked.

I claim as my invention- 1. The combination, with a lock -case, of twohasps pivoted to the lock-case and having notched arc portions adj aeentand parallel to each other and passing in opposite directions throughopenings in the lock-case, substantially as set forth.

2. The combination, in a handcutf, of a lock-case, two hasps hinged tothe lock case and having notched are portions adjacent and parallel toeach other and passing through the lock-case in opposite directions, andspringlatches standing in opposite directions and engaging the notcheson the hasps, substantially as set forth.

3. The combination, in a handcuif, of a lock-case, two hasps hinged tothe lock-case and provided with are pieces notched on their innersurfaces and passing in opposite directions and adjacent and parallel toeach other through the lock-case, spring-latches stand? ing in oppositedirections for engaging the notches, and a bolt adapted to pass inbetween the spring-latches and block the same when the handcnif issecured, substantially as set forth.

4. The combination, in a handcuif, of a lock-case, two hasps hinged tothe case .and having notched are pieces passing through the case inopposite directions and parallel to each other, spring-latches engagingthe notches, a bolt having a projection to pass in between thespring-latches to block the same or to withdraw such latches, therebeing two talons upon the belt, a key to act upon the bolt to projectthe same to lock the handcuff or to withdraw the bolt into a position ofinaction, or towithdraw the bolt and move the spring-latches,substantially as set forth.

Signed by me this 3d day of June, 1891.

HENRY IV. KAIILKE.
